At a Glance & Executive Verdict
Prism MCP
Knowledge & Memory · Local stdio
Quality: 63/100 (Good) | Auth: No auth required
Mneme
Knowledge & Memory · Local stdio
Quality: 48/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Prism MCP if you need specialized Knowledge & Memory tools running via a local process. Choose Mneme if your workspace requires Knowledge & Memory integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Prism MCP when:
You need dedicated capabilities in the Knowledge & Memory domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Zero-config persistent memory for AI agents with local SQLite. Mind Palace web dashboard, time travel (rewind/replay sessions), agent telepathy (cross-client memory sharing), code mode templates, morning briefings, and progressive context loading. 25 tools, 6 resources, 4 prompts.
Vault-native, accountable memory for Claude Code and MCP clients. Markdown is ground truth.
FTS5 BM25 retrieval over the vault with Turkish casefold normalization, plus date, memory-type, and scope filters. Returns ranked hits and EvidenceCards carrying content hashes, trust, confidence, and the backend that actually ran.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Prism MCP is categorized under Knowledge & Memory and uses a local stdio subprocess. In contrast, Mneme belongs to Knowledge & Memory using local stdio subprocess. Select Prism MCP when you need capabilities focused on knowledge & memory and Mneme when you require tools for knowledge & memory.
Retrieves indexed documents by session identifier, date range, and scope. Returns paths, titles, modification times, memory types, and optionally the full markdown body.
mneme_write
Atomically appends or replaces a markdown section in a vault file. Enforces vault path containment and redacts private spans before storage.
mneme_summarize
Groups FTS5 matches for a topic by vault directory within optional date and scope filters. Graphiti enrichment appears only when that optional local graph integration is configured.
mneme_timeline
Returns scope-restricted references for a subject in chronological order. Graphiti facts and bi-temporal filtering appear only when the optional local graph integration is available.
mneme_prime
Builds a token-budgeted preflight context bundle from recent sessions and topic-relevant matches. A caller session identifier enables per-session injection deduplication and full, keypoints, or reference formatting.
mneme_propose
Queues a redacted memory-edit proposal for the policy drain. The server does not apply the edit directly; durable categories always require human approval.
mneme_checkpoint_list
Lists recent Context Continuity Engine checkpoints from the active scope, newest first. Missing checkpoint state returns an empty list.
mneme_working_set_load
Loads salience-ranked working-set items from a Context Continuity Engine checkpoint. Unknown and out-of-scope anchors return the same neutral not-found result.
